Ubuntu 12.04 Extended Security Maintenance

Canonical is providing Extended Security Maintenance (ESM) for the popular Ubuntu 12.04 LTS server release. See the official blog post for more information.

What's covered?

During the official lifetime of an Ubuntu release, Canonical provides security maintenance to binary packages that reside in the main and restricted components of the Ubuntu archive. This FAQ entry contains more information.

During the Extended Security Maintenance phase of the Ubuntu 12.04 LTS release, Canonical will provide security maintenance to a wide range of binary packages that are commonly used in cloud and server workloads. Extended Security Maintenance is included for 64-bit x86 AMD/Intel installations. See the service description for additional details.

Included Kernels

Ubuntu 12.04 LTS initially released with kernel based on version 3.2. The final hardware enablement kernel, when Ubuntu 12.04 LTS reached end of life, was based on kernel version 3.13. Both kernels are included as part of Ubuntu 12.04 ESM.

Exclusions

The following server packages were in main and used enough to be included on the Ubuntu 12.04 LTS installation media but we are not extending ESM to them or their dependencies:

MAAS and dependencies RabbitMQ and Erlang

Python3 (3.2)

Apport and Whoopsie bug reporting

Checkbox system testing tools

Quagga software router

Xen hypervisor

Cups printing stack

Linux Terminal Server Project

OpenJDK

Important: This is not an exhaustive list of exclusions. Please refer to the following section to see the list of packages that are maintained.

Secure Boot

It was not possible to enforce kernel signature verification in Ubuntu 12.04 LTS and, therefore, signature verification of kernels maintained for Ubuntu 12.04 ESM will not be offered.

Maintained Packages

Canonical will provide security maintenance to the binary packages that reside in main originating from the list of source packages below.
